Cool! Is Rust's hash table open addressed?

[sanxiyn]

Yes. It's open addressing, linear probing, Robin Hood hashing.

The program which reached the top of k-n does not use the standard library's hashmap, it uses ordermap: https://github.com/bluss/ordermap

Though that's also an open addressed map.
